Challenge Spreadable Butter is a combination of our highest-quality butter and the finest canola oil. It comes out of the refrigerator soft enough for the most delicate of items. Its pliable texture goes on without waiting and offers a tasty alternative to weak and flavorless spreads. It’s available in 8 oz and 15 oz sizes. The 15-ounce size has an addition of DHA Omega-3, which has been found to support a healthy brain and eyes. Walmart carries a 30 oz package in select locations.
